研究目的:

本研究拟开展多中心前瞻性随机对照研究,验证自发性脑出血术后早期抗凝的安全性与有效性。作为首个聚焦该领域的多中心前瞻性随机对照研究,本研究将填补相关研究空白,为指南更新提供高级别循证依据。  

Objectives of Study:

This study plans to conduct a multi-center prospective randomized controlled trial to verify the safety and efficacy of early anticoagulation after surgery for spontaneous intracerebral hemorrhage. As the first multi-center prospective randomized controlled trial focusing on this field, this study will fill the gap in related research and provide high-level evidence-based basis for guideline updates.
